GE Dishwasher Sump Manifold (WD18X22782)

The GE Dishwasher Sump Manifold is the central hub at the bottom of the dishwasher tub that collects water from the sump and distributes it to the wash arms and other components during the wash cycle. It connects the pump to the spray system and helps maintain proper water flow and pressure throughout the wash and rinse stages.

The GE Dishwasher Sump Manifold can degrade over time due to prolonged exposure to heat, detergent, and hard water minerals that cause cracking, warping, or buildup inside the manifold passages. Physical damage from debris, worn seals, or loose connections can also cause the manifold to leak or restrict water flow to the spray arms.

These symptoms can help you decide if a sump manifold issue matches your problem:

- Dishes come out dirty or poorly rinsed after a full cycle

- Water leaking from the bottom of the dishwasher during operation

- Spray arms receive little or no water pressure

- Standing water left in the tub after the cycle ends

- Visible cracks, warping, or damage on the manifold body

- Unusual noise from the lower tub area during washing

- Detergent residue remaining on dishes after washing
